ANÁLISIS Y OPTIMIZADO DE MAQUINILLAS DE CUBIERTA EN BUQUES ARRASTREROS MEDITERRÁNEOS

Abstract

Due to the deep economical crisis which involves the estuary-fishing sector nowadays, new technical solutions has been searched and developed in order to reduce the manpower aboard in fishing manoeuvres. The Research Group from the Design Group for Automated Production and Manufacturing Institute of the Polytechnic University of Valencia, in collaboration with the naval industry “Basilio Martínez S.L.”, has analyzed and optimized the manoeuvre on deck of trawler boats fishing in the Mediterranean fishing ground. The increasing fixed costs and the lack of manpower have immersed the estuary-fishing sector in a deep economical crisis. New technical solutions have been developed in order to reduce the manpower aboard in fishing manoeuvres, concluding that the most effective key is the design of a new purse seine winch which substitutes the current ones. Nowadays, an excessive number of men is needed for the set out and recovery manoeuvre of fishing gear. Since the staff technical level in this sector is not quite good, the possibilities of failure repairing on service are reduced. New purse seine winches have been proven in several boats of the fisheries sector in the Mediterranean Coast, with successful results. Our study has improved the crew security, has reduced the number of person needed for the operation and the time required for fishing. Keywords: Trawler winch, trawler boats, optimization
